Answer
These values come from an absolute value function.
Work Step by Step
1. Graph all the points.
- Remember that $f(x)$ corresponds to the $y$ coordinate.
2. Connect all the points with line segments.
3. Analyze the drawing and pick the type of function that best fits on:
- Linear: A linear function will be perfect for the first 4 points, but the last one is completely out of the function.
- Quadratic: This type of functions generates a graph with the parabola shape.*
- Exponential: This type of functions creates a curved graph, which is not the case.
- Absolute Value: The plotted graph looks a lot like the absolute value examples*, so it is the type of function that fits those points.
